Concerning the names of two phaeophycean algae: Colpomenia durvillei (Bory) M.E. Ramirez and Utriculidium durvillei Skottsberg

When Skottsberg (1907) described the new genus Utriculidium, he cited 'Aspe rococcus durvillaei Bory ?' as the apparent basionym. The fact that a query was included allows us to treat Utriculidium durvillei Skottsberg as a new name, based on Skottsberg's material from the Falkland Islands and South G eorgia and not based on Bory's material from Chile. The latter material con stitutes the type of Calpomenia durvillei (Bory) M.E. Ramirez. (C) 1999 Ada c/Editions scientifiques et medicales Elsevier SAS.
